Mid-key values give Joseph Duplessis its characteristic quietness - nothing blazes, nothing disappears. Cool hues prevail: blues, greens, and greys anchor the palette's emotional temperature. The absence of saturated colour is itself an expressive choice: this is a palette of restraint and atmosphere. #17141A at 27.4% of the palette: an overwhelming presence that pulls all other colours into its gravitational field. At 6.5%, #7E6939 carries the palette's sharpest chromatic charge: an accent that earns its place precisely because it is withheld. 65 units of value range underpin the palette's structural clarity: the eye always knows where light falls. The mid-to-high key, cool bias, and moderate chroma point to outdoor observation - sky and diffused daylight as the dominant light source. In the context of Joseph Duplessis's full range of palettes, group 4 represents one movement in an ongoing chromatic dialogue.
